To all whom it 'may dof/wem.'

Beit known thatwe, FRANK E. SHArLoB and OTIs D. STORER, citizens of 'the United States,presidin at- Pittsfield, in the county of Berkshire, tate of Massachusetts, have invented certain new and useful Improvements in Fluid-Receptacles, ofl which the .Y following is a specification.

This invention relates to fluid-rece tacles for use in connection with electric` eaters and the like-and has for its 4object the'provision of a device of this character which is' so .reinforced that itdoes not'chang'e its form, as for instance, by bulging or buck1ing,when heated. Our invention relates more specically to receptacles intended for use with electric heatlng units, as for instance, a lat unit ap liedtothe bottom of arece tacle. 20 gVhen the electric heating unit is applied tothe flat bottom of a receptacle it has been found that when the temperature isvraised, the tendency is vfor the bottom to expand or bul e andthereby force the heating unit 'outj ofg intimate thermal relation with the receptacle thereby reducing the eiiiciency of heat transmission.

One of the objects of our invention, therefore, is to overcome this diliculty bylreinforcing the bottom without perforating it. carrying out our invention, we "secure a reinforcing plate to the bottom by means of an adheringr metal, as for instance, b brazing or hard soldering. The dateA 1s preferably flanged, as for instance, y making it cup-shaped so as to give 1t the necessary strength while still maintaining a flat surface for the heating unit;

Other objects of our invention will appear in the course of the following specification, in which we have shown our invention embodied in concrete form for purposes of illustration. j

In the drawing showing the device embodying our invention, Figure 1 represents a fragmentary view of a receptacle and reinforcing plate with a sheet `or strip of soldering metal between them; Fig. 2 shows the same view with heating units applied to it to melt the brazing materiall and secure the parts together; Fig. 3 shows the same device applied `to a flat electric stove. Referring to the drawing, represents a fluid receptacle which may be ofany de- 55 sired shape and material, as for instance,

vtion and heating units,

copper or iron, which is commonly used in receptacles of this character.

v 11 represents areinforcing member, which we have `shown cupshaped so as to ,lit over the Hat heatin unit. -This plate ,may be of any desire material, as for instance, iron. The plate is adapted to substantially cover thesbottom of the receptacle and is to be secured thereto by brazing it to the bottom of the receptacle.` The method of soldering the plate' to the receptacle is shown in Fig. 2 and we regard this method as an important feature, masmuch as `it facilitates the soldering operagives a uniformgjoint. To accomplish this solderingoperation we lace a.' plate -12 of solderln material, suc as a razing or silver sol er alloy, between the receptacle: and the 'reinforcing member. T-wo atlheatin units, 13`and 14, are laced one o'n each `si e to engage` with eac surface, as shown in Fig.. 2, and the bottom and reinforcing plate are pressed together. en 4current is passed through the two the temperature is raised until` the solder melts and the two surfaces are united, .so that when the units are cooled, the bottom of the receptacle and the reinforcing plate actas a unit, thereby preventing the bulging; or buckling of the bote reinforcing plate cup# shaped, we not onlyfstifen it, but also providega recess for the heating unit. The-receptacle is then placedupon the heating unit,'as for instance, an electric stove, as shown in Fig. 3.

While we have shownA ou?l mventlon as being carried outin a specific manner 4in accordance withf the patent statutes, it should be understood that-we do not limit our invention thereto, since various modifcations will suggest skilled in the art, without departing from which is set forth in the annexed clalms.

What we claim as new and desire to se-` cure by Letters Patent of the United States, 1s

1. A huid receptacle having a reinforcing plate secured to the bottom thereof by an adherin metal fused thereto over the entire sur ace.

2. A fluid receptacle havi a reinforcing plate brazed to the bottom lItliereof over its entire surface.
